The medical center went on the modified lockdown while authorities searched for a man who made a threat. Medical center officials said police made contact with the person away from the medical center and that the situation was "no longer affecting the AAMC campus."

In a message sent to the hospital community, officials said there was an incident shortly after 12:30 p.m. in the hospital's emergency department involving a patient and a family member. The message indicated the family member became angry and made a violent threat of harm to the hospital, which prompted the alert status.

Employees are asked to show their identification upon entering. Police or security officers are stationed at all entrances, or those entrances may be locked.

Authorities said they are searching for a man who is about 50 to 60 years old, of medium height and physically fit. He was last seen wearing jeans, a sweater and a blue plaid flannel shirt. He has short gray hair and a well-trimmed short gray beard.

Anyone with information about the man is asked to call hospital security at 443-481-6999.

French magazine Paris Match and German newspaper Bild reported that a video recovered from a cell phone at the wreckage site showed the inside of the plane moments before it crashed.

"One can hear cries of 'My God' in several languages. Metallic banging can also be heard more than three times, perhaps of the pilot trying to open the cockpit door with a heavy object. Towards the end, after a heavy shake, stronger than the others, the screaming intensifies. Then nothing," Paris Match reports.

The two publications described the video, but did not post it on their websites. The publications reported that they watched the videos, which were found by a source close to the investigation.

An official with France's accident investigation agency, the BEA, said the agency is not aware of any such video.

Lt. Col. Jean-Marc Menichini, a French Gendarmerie spokesman in charge of communications on rescue efforts around the Germanwings crash site, told CNN that the reports were "completely wrong" and "unwarranted." Cell phones have been collected at the site, he said, but that they "hadn't been exploited yet."

Menichini said he believed the cell phones would need to be sent to the Criminal Research Institute in Rosny sous-Bois, near Paris, in order to be analyzed by specialized technicians working hand-in-hand with investigators. But none of the cell phones found so far have been sent to the institute, Menichini said.

Asked whether staff involved in the search could have leaked a memory card to the media, Menichini answered with a categorical "no."

Airline: Co-pilot reported depression

Lufthansa, meanwhile, announced that co-pilot Andreas Lubitz told his flight training school in 2009 that he had a "previous episode of severe depression."

The airline is sharing that information and documents -- including training and medical records -- with public prosecutors.

Authorities have said Lubitz purposely crashed Flight 9525 into the French Alps on March 24, killing all 150 people aboard.

His girlfriend knew he had psychological issues but "did not know the extent of the problems," a European government official briefed on the investigation into last week's crash told CNN on Tuesday.

The girlfriend told investigators the couple were working through the issues together and "were optimistic" they could solve the problems; she was just as surprised as everyone else by what he did to the plane, the source says.

The girlfriend also told investigators Lubitz had seen an eye doctor and a neuropsychologist, both of whom deemed him unfit to work recently and concluded he had psychological issues, according to the source.

Investigators are looking into whether Lubitz feared his medical condition would cause him to lose his pilot's license, the source said, adding that while flying was "a big part of his life," it's only one theory being considered.

Another source, a law enforcement official briefed on the investigation, told CNN that authorities believe the primary motive for Lubitz to bring down the plane was that he feared he would not be allowed to fly because of his medical problems.

Lubitz told the neuropsychologist that he was too stressed with work, the European government official briefed on the investigation said.

Official: Lubitz had suicidal tendencies

Earlier, a spokesman for the prosecutor's office in Dusseldorf said Lubitz suffered from suicidal tendencies at some point before his aviation career.

Investigators have not found any writings or conversations where Lubitz shared his motives or confessed to any plans, prosecutor's spokesman Christoph Kumpa said. However, medical records reveal that Lubitz was suicidal at one time and underwent psychotherapy. This was before he ever got his pilot's license, Kumpa said.

Kumpa emphasized there's no evidence suggesting Lubitz was suicidal or acting aggressively before the crash.

The prosecutor's office confirmed what some media outlets had reported about doctors deeming Lubitz unfit to fly, though there were no physical illnesses found.

Recovery efforts continue

While investigators search for clues to Lubitz's motivation, recovery workers continue the grim task of searching for the remains of those killed in the March 24 crash.

The remains of at least 78 people on board the plane have been identified so far using DNA analysis.

Naffrechoux warned Monday that "it may not be possible to find the human remains of all the 150 passengers, as some of them may have been pulverized by the crash."

But French President Francois Hollande, speaking alongside German Chancellor Angela Merkel in Berlin, was more positive, saying that it should be possible to identify all the victims by the end of the week.

A simple stone memorial has been set up at Le Vernet, where grieving relatives of those killed have laid flowers and held prayers.

Safety investigation

The BEA, France's accident investigation agency, said that its ongoing safety investigation was focusing on a more detailed analysis of the flight history leading up to the crash, based on the audio recovered from the cockpit voice recorder and any other available data.

"A deliberate act by a man with a disturbed psychological profile is a possible scenario," BEA spokeswoman Martine Del Bono told CNN. "The first step of the investigation is to describe more precisely what happened."

This will be based mainly on analysis of the cockpit voice recorder, to be supplemented by data from the flight data recorder if it is found, she said.

"But we will also look at other events with possibly similar scenarios, try to understand if there are systemic weaknesses which may contribute or facilitate such scenarios.

"We will in particular look at the cockpit door locking as well as the criteria and procedures applied to detect specific psychological profiles."

On Tuesday, the country's largest e-commerce company announced its new product, Dash.

It's a small Wi-Fi enabled button that lets users add products to their Amazon shopping cart with one click.

Each product has its own designated button, which can be stuck or hung on appliances, cabinets, and anywhere you might want a physical reminder to buy every day necessities. Users receive an alert on their phones once an item is added, so they can change or cancel orders before they're placed.

Amazon Prime members can request an invitation to receive the free device starting Tuesday. It's unclear when the product will start shipping or how much it will cost for non-Prime subscribers.

This smart sticky note is Amazon's latest push into the world of connected devices, and the IoT (Internet of Things).

Earlier this year the company introduced Echo, another connected device that allows people to buy products from its site without having to open a computer or smartphone. The voice-activated cylindrical remote control can also retrieve search results from the web and play music, among other functions, like a virtual home assistant.

Fans of the show scoured Noah's Twitter to learn more about the comedian and found several "offensive" tweets he wrote about overweight women and Jews.
Noah responded to the backlash on Tuesday, via Twitter, saying: "To reduce my views to a handful of jokes that didn't land is not a true reflection of my character, nor my evolution as a comedian."

Comedy Central defended the comedian as well, saying, "Trevor Noah pushes boundaries; he is provocative and spares no one, himself included.

"To judge him or his comedy based on a handful of jokes is unfair. Trevor is a talented comedian with a bright future at Comedy Central."

Comedy Central announced Monday that the 31-year-old South African with three appearances on "The Daily Show" under his belt would take over the show for Stewart, who told told his audience earlier this year that he would be stepping down as host. Noah, who has had a Twitter account since 2009, has a little more than 2 million followers and usually uses Twitter to promote comedy shows or share random observations.

Many Twitter users, including the Anti-Defamation League, have taken to the platform to show their distaste for his tweets.
